摘要
The need for sustainable fuels has resulted in the production of renewables from a wide range of sources,in particular organic fats and oils.The use of biofuel is becoming more widespread as a result of environmental and economic considerations.Several efforts have been made to substitute fossil fuels with green fuels.Ester molecules extracted from processed animal fats and organic plant materials are considered alternatives for the use in modern engine technologies.Two different methods have been adopted for converting esters in vegetable oils/animal fats into compounds consistent with petroleum products,namely the transesterification and the hydro-processing of ester bonds for the production of biodiesel.This review paper primarily focuses on conventional and renewable biodiesel feedstocks,the catalyst used and reaction kinetics of the production process.
